Cashews and Histamine

Cashews. They’re delicious, nutritious and versatile. But can they be eaten by people with histamine intolerance (HIT)?

Opinions are divided. One blogger, who says she is a “holistic health coach”, actively encourages people with HIT to eat cashews. On the other hand, Dr. Amy Myers, writing for Mindbodygreen, lists cashews under “Histamine-Rich Foods”, as does the website for Histamine Intolerance Awareness UK.

Histamine intolerance specialist Dr Janice Joneja says: “Unless the person is allergic to them, the following are generally safe on the histamine-restricted diet as long as they are free from any additional ingredients – Pure nuts and seeds, which includes sunflower seeds, cashew nuts and coconut and their derivatives such as coconut or cashew milk. The only seeds restricted are pumpkin seeds.”

Other histamine experts insist that coconut and all nuts and seeds should be avoided. Indeed, the world of histamine intolerance can be confusing!

Which is exactly why “Is Food Making You Sick” is all about the “STRICTLY Low Histamine Diet”. According to the old saying, “It is better to be safe than sorry”, this book lists as “safe” only the foods upon which all reputable authorities agree. Not everyone agrees that cashews can be included in a low histamine diet so we recommend that people with HIT should avoid them.

Of course, the low histamine diet is not a life-long diet. It is a diet to lower your histamine to safe levels. When you’ve been on the diet for long enough to feel better, you can gradually and slowly re-introduce small quantities of additive-free cashews (or other histamine-rich foods) into your diet, while carefully monitoring your health.

The List of Low-histamine Foods is Scientifically Researched.

Maybe you’re on a low-carb diet. Maybe you’re on a sugar-free diet, or an anti-inflammatory diet, or a fruitarian diet, or some other popular eating regime. That is your choice, but if you are histamine intolerant, your symptoms are not likely to subside unless you choose low-histamine foods and avoid foods (and external factors such as stress and pollution) that raise your body’s histamine levels.

Some popular diets are negotiable. Take the Paleo diet, for example – there is debate about whether Stone Age humans ate grains. Paleontologists have found traces of grains on ancient stone cooking tools dating back 105,000 years.

Some people say that grains can be eaten on a Paleo Diet, while others insist that grains are forbidden. In other words, the foods included in this diet can be considered “negotiable”.

The foods in a gluten-free diet, on the other hand, are non-negotiable. Either there’s gluten in the food or there isn’t. Your body certainly knows the difference! Scientists have tested foods to reveal their gluten content.

Don’t mix your diets!

The same applies to low-histamine foods. For his book “Is Food Making You Sick?” James L Gibb did not “invent” the low-histamine food list. The foods on the list have been selected because they have been scientifically proven to be low in histamine or low in factors that cause histamine release. These foods do not necessarily conform to the pattern of other diets. However this is due to sheer necessity!

As one Amazon commenter said in reply to a reviewer who complained about the book’s food list:

“Go ahead and follow your “anti-inflammatory” diet but it’s not the same as a low histamine diet. Choose which diet you need to follow, you can’t be on both. If you’re not histamine intolerant, then don’t follow a low histamine diet. The low histamine foods in the book were not selected on the basis of the latest food fads and crazes. They were selected on the scientific basis of how they affect people’s histamine levels. This is a fixed property of foods and cannot be changed according to people’s whims. Just because you don’t like to eat a certain food does not mean it is not low in histamine.”

Of course you can select your favorite foods from within the low-histamine food list, although we do encourage you to eat as wide a range of foods as possible from within the list, to maximize nutrition. If the range of foods seems very different from whatever diet you’ve previously been following, maybe that’s the reason why your symptoms are continuing. The Strictly Low Histamine Diet does not necessarily resemble any other diet. People who are NOT histamine-intolerant can go ahead and choose some popular diet craze to follow, but many of us do not have that luxury. As soon as our histamine levels rise, we suffer.

As mentioned before in this blog, following too many diets at the same time is not a good idea. It can overly-restrict your food choices. Find out if you’re histamine-intolerant (it’s easy to do, as the book describes). If you are, then there’s an excellent chance that going low-histamine will help you return to good health.

Low Histamine Food Lists

The Internet offers many ‘low histamine’ food lists. Reading them all can be confusing, because they often contradict each other. Low histamine food lists are not as simple as, say, gluten-free or lactose-free food lists, because gluten and lactose are either found in a food or they are not. Their existence is independent of storage conditions and freshness.

Histamine levels, by contrast, fluctuate. A food might be low in histamine to begin with, yet high in histamine as it ages. Histamine levels in food also vary depending on the storage methods (e.g. freezing halts histamine development).

Furthermore, some of these published lists include foods that may not have high histamine levels, but which contain compounds that provoke histamine release. Others do not.

Many low histamine food lists do not take into account foods that may be DAO blockers. Moreover, they may not include mention of oxalate (oxalic acid), an irritant that can trigger histamine release, thereby causing the same symptoms as histamine. Oxalates can also contribute to the distress and debility of chronic fatigue syndrome and myalgic encephalomyelitis, because they damage and destroy mitochondria. High levels of oxalate in the intestines also hinder beneficial bacteria from colonizing the gut.
Nor do many food histamine lists consider foods that release other biogenic amines, those which may contribute to HIT and which certain foods may release in some individuals, despite the fact that the foods themselves may not contain any biogenic amines.

To add to the confusion, some individuals have published lists of foods which are tailored to their own unique body chemistry. That is, they themselves might be able to tolerate the foods on their list, but most other people cannot. One “low histamine” recipe-writer, for example, recommends using lentils, cocoa, berries and thyme, despite the fact that SIGHI (Swiss Interest Group Histamine Intolerance) describes lentils as “incompatible.” Histamine expert Dr Janice Joneja says, “Berries tend to be high in benzoates. Benzoates release histamine.” And, “There are certain herbs which release histamine. Thyme, for example, releases histamine.” Cocoa contains compounds that are known histamine liberators.

Another person who blogs about mast cells has published “low histamine” recipes that include ingredients such as mushrooms, split peas, squash and quorn, all of which are described as “to be avoided” in numerous authoritative low histamine food lists from around the world.

Even the most authoritative lists, compiled by medical researchers, can have disparities. There is disagreement about a wide range of fruits, vegetables and spices including cherries, grapes, cranberries, blackberries, peaches, apricots, nectarines, pears, black-currants and red-currants, blueberries, kiwi-fruit, pineapple, plums, papaya, mushrooms, broad beans, pumpkin, anise, cinnamon, nutmeg and cloves.
Legumes and pulses are also debatable. Some lists include non-soy legumes such as dried beans and peas and lentils. All lists ban soy and red beans.
Again, some lists ban all nuts, while others forbid only walnuts, pecans and cashews.

This is why “Is Food Making You Sick? The Strictly Low Histamine Diet” recommends only those foods which have been agreed upon by every genuine, science-backed and meticulously researched source. The low histamine food list in this book is strictly low histamine, as are the recipes.

Don’t panic about gluten!

Some people believe that if you suffer from histamine intolerance you should go gluten free.

These days, there is a fashion for avoiding gluten-containing foods because ‘gluten free’ is perceived as ‘healthier’. Gluten-containing foods include wheat, barley, rye, triticale, kamut and spelt.

Gluten is a natural plant protein that helps bread rise and gives bread, cakes, pastry, pasta, noodles, and similar foods their elasticity and texture.

The truth is, gluten is only a problem for people who are non-celiac gluten sensitive (NCGS), or who have celiac disease – that is, approximately 1% of the population. (Note: NCGS is a condition that is distinct from celiac disease.)

Foods that happen to contain gluten may also be a problem for people who are sensitive to those particular foods. For example, you may not be celiac or NCGS, but you might have been diagnosed as being sensitive to wheat, for reasons other than its gluten content. People with histamine intolerance should avoid wheat germ, in any case.

If you have celiac disease or NCGS then it is vital to avoid gluten because it can cause intestinal permeability, which is also known as ‘leaky gut’. This can in turn lead to DAO insufficiency and thus to histamine intolerance. Gluten intolerance is also linked with autoimmune diseases.

However if you are, like the vast majority of the population, perfectly capable of digesting gluten without any problems, gluten-containing foods are actually good for you. They are highly nutritious – packed with vitamins, minerals and beneficial fiber.

“Studies show that whole grain foods, as part of a healthy diet, may help lower risk of heart disease, type-2 diabetes, and some forms of cancer. A 2005 report from the American Dietetic Association warned that gluten free products tend to be low in a wide range of important nutrients, including B vitamins, calcium, iron, zinc, magnesium, and fiber. There’s also little point in eliminating just some gluten. For people who are sensitive, even trace amounts can cause damage to the small intestines. So an almost gluten-free diet isn’t going to help if you have a problem.” [Source: WebMD]

In a normal, healthy person gluten will not cause a leaky gut. And the odds are, you are one of the 99% who can digest gluten.

If you think you really might be celiac or have NCGS, ask your doctor for a test. The Celiac Disease Foundation states that there are several blood tests available that screen for celiac disease antibodies. “If test results suggest celiac disease, your physician will recommend a biopsy of your small intestine to confirm the diagnosis.”

Even if your celiac test comes up negative, you could try avoiding all gluten for at least 30 days to see if that makes your health improve. If you do feel better, this might indicate that you have NCGS.

If you really are gluten intolerant you’d have to cut out all gluten, down to the tiniest particle. An ‘almost-gluten-free’ diet will not help at all.

Simply avoiding gluten because you think it’s ‘bad’ for you means cutting a lot of nutritious foods from your diet. You can, of course, do so if you wish, but-

it’s more than likely there will be no benefit in it

you’d have to cut out a wide range of foods, because if you check the ingredients on labels, there are traces of gluten in most pre-prepared foods

Antihistamines

If you find that taking certain antihistamines significantly improves your health, then it’s likely you suffer from HIT (Histamine Intolerance). Some common antihistamine trade names include:

Zyrtec = cetirizine, an antihistamine that works by blocking histamine (H-1) receptors.
Zantac – ranitidine, an antihistamine that works by blocking histamine (H-2) receptors.

Both of these – like any medications – can have unwanted side effects. However, these are generally outweighed by their benefits, at least in the short term. Taking them is a good way to hit your symptoms hard and really get them to settle down. If you wish to follow up the potential side-effects of Zyrtec and Zantac, click on these links: ZantacZyrtec

That said, taking Zantac and Zyrtec is not a long-term solution. It’s like putting a bandage over an infected wound – it looks okay from the outside but the problem remains. Besides, over time the body can develop resistance to the meds. Then they gradually lose their efficacy and you go back to ‘square one’.

About Boosting Your DAO

We suggest that HIT sufferers:

Make sure none of your other medications (if any) are DAO (diamine oxidase) blockers, which might have brought on your symptoms in the first place. If possible – and under medical supervision – try to wean off them.

Stick to the Strictly Low Histamine Diet and its associated dietary supplements. A low histamine diet with safe, natural supplements has no unwanted side effects and for many people it has provided that ‘miraculous’ relief they have been seeking. It doesn’t take months and months to get a result – only a few weeks.

Another essential is dietary fiber. Consuming abundant fiber has been proven, in numerous studies, to decrease inflammation in the body (and the reverse is true of a high fat diet). It can actually improve the binding ability of the histamine H-1 receptor.

Stress can be a powerful trigger for Histamine Intolerance too, so it’s important for people with HIT to treat themselves kindly and allow themselves time to relax. For anyone with HIT who is reading this post, we recommend visiting the Helpguide website and looking at their excellent Stress Management Guide.

Protect and heal your intestinal mucosa. The body produces DAO in the small intestine, the upper part of the large intestine, and the kidneys. To help protect and heal the mucosal lining of your intestines, include the spice turmeric and brassica vegetables (e.g. cabbage, cauliflower, broccoli, Brussels sprouts, )in your diet. Prebiotics and probiotics, too, play an essential role in the healing of the gut.

Protect and heal your kidneys. Your kidneys may be perfectly healthy, but there are still things you can do to make sure they stay that way – and to boost their DAO producing capabilities. The Kidney Foundation of Canada recommends that people with kidney disease should ‘control your salt intake and avoid foods with a high sodium content. These include processed foods like “deli” meats, canned foods, convenience and “fast” foods, salty snacks and salty seasonings.’ They also say, ‘Phosphorus is a mineral which normally keeps your bones strong and healthy. However, too much phosphorus may cause itchy skin or painful joints. When the kidneys start to fail, your blood phosphate level will rise. Therefore, you may need to limit certain foods which contain even a moderate amount of phosphorus. These include milk, cheese and other milk products, and protein foods such as meat, fish and poultry.’

Quercetin for Histamine Intolerance

Quercetin, a type of plant-based chemical or phytochemical known as a flavonoid, is highly beneficial for histamine intolerance sufferers. Quercetin reduces the release of histamine, the substance that triggers allergies. Histamine is produced by mast cells.

In allergic rhinitis, mast cells in the nasal area increase in number and are thought to play an important role in the nasal symptoms that occur during seasonal allergies. In one study, researchers triggered histamine release in nasal scrapings from seasonal allergy patients exposed to mite antigen. When the nasal scrapings were exposed to quercetin, histamine release was inhibited 46 percent to 96 percent.[6] In another study of rat mast cells exposed to an allergen, quercetin inhibited histamine release by 95 percent and 97 percent. [7]

Other Health Benefits

Quercetin has been linked to a number of other health benefits. Scientific research proves that not only does it possess potent antioxidant and anti-inflammatory properties [1], it also exerts a cognitive enhancing effect on the brains of Parkinson’s Disease patients [2] and protects against cadmium-induced oxidative toxicity and therefore may ameliorate autism symptoms [3].

‘Particularly notable was a study conducted by researchers at the Institute of Food Research and published in the journal Atheroscleroisis in 2008, which addresses concerns that, while quercetin has been shown to be highly effective in laboratory experiments on cell lines, the antioxidant quickly breaks down in the stomach and intestines when ingested as part of the diet. Quercetin skeptics had suggested that, because of this quick breakdown, quercetin naturally consumed in foods such as apples would have little or no health benefit.

‘The 2008 study showed, however, that both quercetin and the metabolites produced when it breaks down in the digestive system act as anti-inflammatories on the cells of human blood vessels. This suggests that dietary quercetin would indeed have the heart and blood pressure-promoting health benefits that had been observed in laboratory studies.

‘Another study, published in the American Journal of Epidemiology, found that a high dietary intake of flavanols decreases the risk of pancreatic cancer by 25 percent in non-smokers and by more than 50 percent in smokers. When the researchers examined dietary intake of quercetin in isolation, rather than intake of flavanols in general, they still found a reduction in the risk of pancreatic cancer.’ [3]

One clinical study of people with a strong inherited tendency to develop colorectal cancer found that the combination of quercetin and curcumin supplements decreased the number and size of precancerous rectal tumors. [4] No other clinical trials testing quercetin’s ability to prevent or treat cancer have been reported in the medical literature. Clinical trials are needed to further clarify quercetin’s possible benefits. In addition to cancer prevention and treatment, preliminary studies have also suggested potential value for quercetin in prostatitis (inflamed prostate) and heart disease. Further studies are needed before any recommendations can be made. [5]

Food Sources of Quercetin

Good sources for HIT sufferers include apples (particularly apple skin), onions, broccoli, green beans, leafy green vegetables such as lettuce; celery, chives, coriander and dill. One tree ripened apple, for example, contains 50 mg of quercetin. Quercetin is also available as a dietary supplement.

Quercetin is not destroyed by most cooking methods, including frying and baking. It is however lost by boiling food in water. ‘The boiling of onion leads to about 30% loss of quercetin glycosides, which transfers to the boiling water.’ [8]

[3] Quercetin protects against cadmium-induced oxidative toxicity
Sunday, October 20, 2013 by: David Gutierrez, staff writer, Natural News
‘The common antioxidant quercetin may counter the toxic effects of cadmium on the body, according to a study conducted by researchers from Zhejiang University in China and published in the journal Anatomical Record in 2010. Cadmium is a highly dangerous and widespread heavy metal that has been linked to cancer, impaired brain function and development and damage to organs including the lungs, kidneys and bones. According to a groundbreaking study by Arizona State University researchers that was published in the journal Biological Trace Element Research earlier this year, high blood levels of cadmium are one of the single strongest factors linked to the severity of autism symptoms. The Center for Disease Control and Prevention (CDC) lists cadmium as number seven among the 275 most hazardous substances.’

Histamine and Heartburn

Many people with histamine intolerance regularly take medications to control heartburn.

Histamine acts to increase hydrochloric acid secretion by cells in the stomach lining. An overload of histamine can cause the production of excess stomach acid, which is why one of the treatments for heartburn is the H2 antagonist Ranitidine.

Pantoprazole is another drug for heartburn patients that decreases the amount of acid produced in the stomach. The problem is, long-term treatment with pantoprazole may also decrease the body’s ability to absorb vitamin B-12, resulting in a deficiency of this vitamin.

Vitamin B12 Deficiency

Symptoms of a vitamin B-12 deficiency may develop slowly and include pale skin, weakness, tired feeling, shortness of breath, and a fast heart rate. Vitamin B12 deficiency can potentially cause severe and irreversible damage, especially to the brain and nervous system. When levels of B12 are only slightly lower than normal, they can lead to a range of symptoms including fatigue, depression and memory loss.

Foods richest in Vitamin B12 may cause problems

Foods richest in Vitamin B12 include shellfish, liver, fish, crustaceans, fortified soy products, fortified cereals, red meat, milk, cheese and eggs. Most of these foods are also high in histamine, and are best avoided by people with histamine intolerance. Fortified cereals are processed foods with B12 (not methyl B12) added to them by the manufacturer.

Problems with Vitamin B12 absorption

Furthermore, not everyone is able to absorb Vitamin B12, even if they eat foods that contain it. The human physiology of vitamin B12 is complex, and therefore may go awry, leading to B12 deficiency.

Health conditions that may lead to poor B12 absorption include:
Atrophic gastritis (thinning of the stomach lining)
Pernicious anemia
Surgery that removed part of the stomach or small intestine, including weight loss surgery
Conditions affecting the small intestine, such as Crohn’s disease, celiac disease, bacterial growth, or a parasite
Heavy drinking
Immune system disorders, such as Graves’ disease or lupus
Long-term use of acid-reducing drugs, e.g. Pantoprazole.
A strictly vegan diet
A vegetarian diet that does not include enough eggs or dairy products to meet vitamin B12 needs
Advanced age

Cyanocobalamin is synthesized using cyanide

One way to combat Vitamin B12 deficiency is to take supplements. However, most Vitamin B12 supplements are in the form of cyanocobalamin rather than methylcobalamin.
Cyanocobalamin is artificially synthesized in laboratories. One of the main ingredients is potassium cyanide – yes, you read it right – cyanide, the well-known poison. Cyanocobalamin is the form used in most pharmaceutical preparations because adding cyanide stabilizes the molecule.
When we ingest cyanocobalamin, we are being exposed to small amounts of cyanide.

Methylcobalamin is more easily absorbed

Furthermore, cyanocobalamin is harder for our bodies to metabolize than methylcobalamin. Many people with histamine intolerance are, without being aware of it, ‘undermethylators’. Undermethylation, or ‘histadelia’, is an inherited condition characterized by elevated blood levels of histamine.
If our bodies cannot properly methylate vitamin B12, they cannot adequately absorb it. Methylcobalamin is already methylated, and thus more easily assimilated into the body.

If you are histamine intolerant – or even if you’re not – the optimum way to make sure you’re not Vitamin B12 deficient is to take methylcobalamin. It is available from pharmacies as pleasantly-flavored pills or drops, to be dissolved slowly under the tongue.

For those who are interested in finding out more about how to obtain methylcobalamin, we’ve provided a link below (click on the picture).

Sciatica

According to Dr. Heinrich Kremer of the Cell Symbiosis Therapy Academy,

‘Histamine dilates the small blood vessels to make them permeable to larger immune cells. It also causes fluid to move from blood vessels into the tissues. This leads to swelling and pressure on nerves of the affected tissues, which can lead to migraines, painful tension in the throat, neck, spine, thigh and adductor muscles.
Acute inflammation can also cause temporary arthralgia and neuralgia (rheumatism, sciatica, lumbago, trigeminal neuralgia).’

High-protein diets shorten lifespan, two studies say

People on high-protein diets are likely to lose years of life along with the weight they shed, according to two studies.
It’s nearly as bad as smoking, says Dr Valter Longo, co-author of a study in the journal Cell Metabolism.

The most healthy mix is a high-carbohydrate, low protein diet, say Australian scientists who have published a study in the same journal.

This leads to increased body fat, but a longer lifespan, say the scientists from the University of Sydney’s Charles Perkins Centre. They tested 25 different diet combinations on 900 mice to see what happened to their appetite, metabolic health, ageing and lifespan.

“We need to look at where the calories come from and how they interact.” Although the mice on a high-protein diet ate less and were slimmer, they also had a reduced lifespan and poor heart and overall health.

Those on a high-carbohydrate, low-protein diet ate more and got fat, but lived longest.

The mice that ate a high-fat, low-protein diet died quickest. “It is an enormous leap in our understanding of the impact of diet quality and diet balance on food intake, health, ageing and longevity,” Prof Simpson says.

Co-author Professor David Le Couteur says the study is an important step towards understanding what constitutes a healthy balanced diet.

It indicates it might be beneficial for people to eat the right diet in the right proportions and let the body dictate the correct amount of food.

“If people want to live long, healthy lives they can look at their diet and exercise. That will do more good than taking all the pills in the world.” He says the healthiest mice had the lowest levels of the branched-chain amino acids derived from animal protein and often used by body builders The results are entirely parallel with the US study.

They found meat, fish and dairy products are probably causing harm.

“We provide convincing evidence that a high-protein diet, particularly if the proteins are derived from animals, is nearly as bad as smoking,” says the University of Southern California’s Dr Longo.

His study analysed the diet of 6831 middle-aged and older adults.

Those who derived more than 20 per cent of their calories from protein were four times more likely to die of cancer or diabetes than other people.

Fatal histamine poisoning

Earlier in 2014 two people met a tragic death after eating fish. The culprit was found to be scombroid poisoning.
Scombroid poisoning is a now-outdated term for histamine fish poisoning. It is also sometimes known as pseudoallergic fish poisoning, histamine overdose, or mahi-mahi flush.
Histamine is colorless, odorless and tasteless. Scombroid fish histamine poisoning is hard to detect without scientific equipment, and can be fatal.
‘The term scombroid was used because the first fish species implicated in this poisoning were from the suborder Scombridae, which includes mackerel, tuna, marlin, swordfish, albacore, bonito, skipjack, and almost 100 other species (Scombridae is derived from the Greek word scombros, which means mackerel or tunny). The term histamine fish poisoning is now considered more appropriate because many cases are from nonscombroid fish. Examples include mahi-mahi (dolphin fish), amberjack, herring, sardine, anchovy, and bluefish.’

Doctor warns scombroid poisoning involved in Bali death of Noelene and Yvana Bischoff is not rare

A BRISBANE doctor who treated his wife for the same type of food poisoning which killed a Queensland mother and daughter in Bali says the illness is more common than most people think.

Noelene and her 14-year-old daughter Yvana Bischoff died while holidaying in Bali in January.

The subsequent autopsy indicated that they died from a combination of scombroid poisoning from food that was suspected to be tainted and existing medical conditions.

Experienced Daisy Hill general practitioner Nick Stephens cautioned that scombroid poisoning is actually not that rare, after treating his wife for it last year.

“It’s the most common form of fish poisoning in the world,” Dr Stephens said.

“But on the other hand, the complication of death (resulting from scombroid poisoning) is rare.”

Having been in the industry for 35 years, Dr Stephens was stunned when his wife Lorraine turned up at his clinic on Melbourne Cup day last year with systems of scombroid poisoning.

Mrs Stephens had been out for lunch at a South Bank restaurant when she and three friends had a major reaction about ten minutes after eating mahi mahi fish – the same variety the Bischoff’s had consumed shortly before their deaths.

Dr Stephens, 64, said when his wife arrived at his work she was bright red, having palpitations and struggling to breathe.

“I’ve never seen a patient ever look so red with a headache and the palpitations. So, obviously, with a severe dosage it can kill,” he said.

Dr Stephens said an analysis of the symptoms left him in no doubt that his wife had suffered from scombroid poisoning, even though it can be difficult to confirm.

“You cannot run a blood test or doing anything else to confirm it,” he said.

“They’ve had exactly the same problem with these people overseas, they can’t confirm it but they can’t find anything else.”

Since the attack, she has suffered from pancreatitis, which her husband believes may be a rare complication from scombroid poisoning.

Breaking News

Note: The team behind “Is Food Making You Sick? The Strictly Low-histamine Diet” is always updating the book to reflect the latest scientific research. Look for the 2017 edition. The date is printed on the front cover and on the title page.

Flaxseeds (the 2014 and 2015 editions) are no longer listed as suitable for people with histamine intolerance.

Despite still being listed as “well-tolerated” by the Swiss Interest Group Histamine Intolerance (SIGHI) and other reputable sources, coconut is no longer recommended for HIT sufferers. It has been added to the “foods to avoid” list in the book. Recipes in the 2017 edition have been revised accordingly.

The Strictly Low Histamine Diet is just that – strict. Our aim is to exclude any foods that possess even a minimal chance of aggravating the condition.
